MEMORANDUM DEVICE.

Specification of Letters Patent.

Patented Apr. 5, 1921.

Application filed July 21, 1919. Serial No. 312,276.

To all whom t'may concern:

Be it known that I, JOHN B. BRADY, a citizen of the United States, residin at Somerset, county of Montgomery, and tate of Maryland, have invented a certain new and useful Improvement in Memorandum Devices, of which the following is a specification.

My invention relates broadly to calculating machines of the type having means for recording printed characters on a paper strip, and more particularly to an attachment to permit notations to be readily made in hand writing on the paper strip.

The object of my invention is to provide a simple device capable of being produced on a quantity basis which can be attached to all makes of calculating machines to form a bearing surface over which the paper strip is guided for the purpose of writing by hand on the strip as it feeds through the machine.

The attachment will be more clearly understood by reference to the accompanying drawings in which- Figure 1 is a schematic diagram showing.

the relative arrangement of the attachment applied to an adding machine; and Fig. 2 is a perspective view of the attachment showing a portion of the paper strip threaded over the bearing surface.

The desirability of this device will be apparent when it is considered that lengthy columns of computations can be readily marked by pencil with any pertinent notations for immediate reference, or, if necessary, the original figures preserved as a permanent record bearing explanatory notes.

Referring )articularly to Fig. 1 of the drawings ref erence character 1 indicates the addin machine equipped with the usual carriage trame 2 carrying paper supply roll 3 arranged to feed paper strip 4 over the platen 5. The keyboard of the machine actuates the usual set of type members for re cording printed characters on the paper strip st. Numeral 6 represents the attachment which is the subject matter of the present invention. The device 6 comprises an extended flat bearing surface supported horizontally above the carriage frame 2 by depending side members 7 and 8. Fig. 2 is a more detailed view of the attachment. The side members 7 and 8 are secured to the sides of carriage frame 2 by suitable screws 13 and 11 registering with threaded holes 9 and 10 in members 7 and 8, rcspce tively. The fiat bearing surface is die pressed at 12 and 14 forming raised guide members under which the paper strip 4 is threaded and maintained continuously against; the bearing surface as the strip feeds through the machine.

In the operation of the adding machine the paper strip 4I is automatically reeled oil of supply roll 3 over platen and is threaded under guide member 12 against flat surface 6 and under guide member let where it is free ended. The printed characters indicated at 15 are recorded as usual on the pa per strip and pertinent notes made in hand writing as shown at 16 for further referonce.

It will be readily understood that the device described may be attached to any type of calculating machine employing a recording paper strip and is not limited as an attachment to the particular design of adding machine illustrated.

It is further obvious that the device as manufactured is adapted for attachment to a variety of machines in addition to its use on adding machines as illustrated and that my invention is only limited by the scope of the appended claims.

Having thus described my invention what I claim is 1. An attachment for machines having means for supporting a paper strip, said attachment comprising a flat extended portion and side members integral therewith and adapted to be secured to said machine to su Jport said flat extended portion, substantially as described.

2. An attachment for machines having means for supporting a paper strip. said attachment comprising a bearing surface and side members integrally connected therewith and adapted to be secured to said machine to support said bearing surface, substantially as described.

3. An attachment for machines having means for supporting a paper strip, said attachment comprising a flat extended portion and side members integral therewith 4. An attachment for machines having means for supporting a paper strip, said attachment comprising a flat extended portion, means integral with said flat extended portion for guiding said paper strip continuously thereagainst, and side members integral with said flat extended portion adapted to be secured to said machine to support said fiat extended portion, substantially as described.

5. An attachment for machines having means for supporting a paper strip, said at: tachment comprising a unit sheet of material formed with a flat extended portion, means for guiding said paper strip continuously thercagainst, and side members adapted to be secured to said machine to support said fiat extended portion, substantially as described.
